RE7.A. - Page 209 Expansion Project#:11637 lury��,LV1L Page 4 MAXIMUM SCENARIO FOR AIR QUALITY PURPOSES For the purposes of the air quality analysis,vehicle trips and queuing for a scenario assuming that the existing Redwood City Costco Gasoline station trip generation doubles in the future was requested. From a transportation standpoint, this is not reasonably likely to occur but the data request for this scenario is provided in Tables 5, 6, and 7.

The existing Redwood City Costco Gasoline station generates a total of approximately 200 vehicles during the weekday p.m. peak hour (400 total trips).At other hours of the day when it is open, the existing fuel station generates as few as 25 total vehicles (or 50 total trips). Averaging the total number of weekday daily trips over an assumed daily operating duration of 14 hours equates to an average of approximately 175 total vehicles per hour. Doubling the daily trip generation would Kittelson&Associates,Inc. Boise,Idaho
